Big Horn Fishing Report: Trout, Walleye & More Biting on the Bighorn River and Lake

Fishing Report for Big Horn, Montana - April 11, 2025 Good morning, anglers! If you're planning to hit the waters in and around Big Horn today, you're in for a solid day of fishing. The weather is looking favorable with clear skies, light winds, and temperatures ranging from the mid-40s in the morning to around 56°F by mid-afternoon. Sunrise was at 6:33 AM, and sunset is at 7:49 PM, giving you plenty of daylight to land that big catch. The Bighorn River is in exceptional condition as water flows are steady around 707 CFS. Temperatures remain cool but fishable, and the water clarity is ideal for both nymphing and streamer tactics. Recent catches include plenty of healthy Brown and Rainbow Trout, averaging 14 to 20 inches, with some larger ones in the mix. Fish are active in the deeper runs, and even surface action is starting to pick up during the warmest parts of the day. For tackle, the best nymph patterns this week have been sowbugs, scuds, perdigons (purple and pink), BWO nymphs, and Cotton Candies. For streamer enthusiasts, patterns like Rusty Trombones, Thin Mints, and Ice Cream Cones have been highly effective, especially when worked through the deeper pools and seams later in the day. Spin anglers, don’t shy away—try gold or rainbow-colored Rapalas and Panther Martin spinners for consistent action. If you’re fishing Bighorn Lake, the walleye bite is picking up. Brown and rainbow trout are also feeding actively, particularly during mid-morning hours. Jigs tipped with plastic worms or minnows are your best bet. For those targeting perch or crappie, stick to slower retrieves near rocky structures with smaller artificials. Hotspots to consider today include: 1. **Three Mile Access on the Bighorn River** – Excellent for both wading and floating anglers, with deep slots holding plenty of trout. Nymphing here is a surefire way to land fish. 2. **Afterbay Dam** – A classic and reliable spot on the river, particularly with streamers and midges. 3. **Bighorn Lake** – Head towards the Montana end for some great walleye action or shoreline trout fishing with crankbaits or spinners. April is a prime time to fish the Big Horn area, and with low angler pressure today, you’ll have plenty of water to yourself. Dress in layers for the cool morning but be ready to shed them as the sun warms things up. Tight lines, and may the fish be biting!
